Works efficiently compared to older models. Important gadget to have around for jump start and to pump up tires. Also, Sam's Club honors the Fatmax warranty well. My previous one died after 6 months, Sam's Club refunded the cost price right away.

Seems to be a great product. It’s a brand new item for me. Much better than the corded compressors I have used in the past.

Thought this would be a great gift for my son but turns out it won’t hold a charge and took over 30 mins to barely inflate a 40psi tire, which in turn drained the battery. This was highly disappointing considering the price. Will stick with the better yellow and black name brand for better quality

Does what it says... IF IT HELD A CHARGE. This would be okay if you can keep it plugged in at home every day/every other day). Mine needed to go with me in the car, but any time I needed it there wasn't enough power to jump my car, %26 would die while trying to jump if not already dead). It needs 110% charge to jump a vehicle, which it never had bc the second I unplugged the dc cord and put in car it started losing charge, was dead within 1 day from the get go. Just tonight my neighbor came to jump my car, pulled out his jump start, and his was dead as well... it's been hours %26 it still isn't charged enough to jump, and his is the least powerful model. It needs to be able to jump while plugged in, to charge from the car, or something to be more practical/useful

I had a similar unit, this one is just as good, it will jump anything.

Got this for my husband to use on the boat or for the truck.

Love this! So easy to use and works great!

Gave this to my college kid who drives back and forth on country roads. He had to use it within the month and would otherwise have been stranded for some time.

We have an earlier version of this Stanley jump start / Compressor / USB power unit and have loved using it. We purchased this new one and have been very disappointed. It can be used much the same, but instead of recharging in 4-6 hours it takes 40. instead of pluging into the wall it has a tiny 9 volt external charger which gets so hot while charging you dont want to touch it. I will not wait for nearly 2 days to be able to use it after the battery is used up and the high temperature does not seem safe. We are returning it and will try to find another brand designed like our earlier Stanley.

Why would they not attach the charger permanently to the unit? Or a compartment to store it. They want you to lose it... I expected better. Charge 5 more dollars and make a quality product.
